Spain is located in southwestern Europe on the Iberian Peninsula and is bordered by Portugal, France, and the Mediterranean Sea. The country has one of the world's oldest wine traditions, with viticulture introduced by Phoenicians and later expanded under Roman rule. Today Spain possesses the largest vineyard area in the world and produces a wide range of wine styles.
Spanish vineyards are spread across diverse climates, from the cool Atlantic regions of the northwest to the hot interior plateau known as the Meseta. Mountain ranges and river valleys create many distinct terroirs that influence grape growing and wine production.
Spain uses a regulated classification system aligned with European PDO and PGI designations.

Spanish wines range from powerful red wines aged in oak to fresh Atlantic whites and fortified wines such as Sherry produced in southern Spain.
Spain remains one of the most influential wine-producing countries in the world, combining traditional practices with modern winemaking techniques.
